Editor's note: These lectures were originally issued privately and did not
receive full publication in book format till Weiser's edition in
1975. Since then many of them have been printed by small publishers in a handy
pamphlet format. Several sites have also published the whole series of 10
lectures on the internet, such as the following:

All of the above are based on scans of the original editions,
and therefore contain errors. The purpose of publishing these
lectures has been to update them in accordance with the presentation of the rest of the Masseian corpus
published here. We have now cross-referenced the data contained in these
lectures to the rest of the
corpus (see the General Index),
and have now provided full references which would have otherwise been
absent in any other of the published editions.
